SELF-SUPPORTING SABH.

appnoauon mea umass, 1m. semi no. sues.

My invention relates to devices for holdin? window panes, and more particularly to se f detailsof the invention will appear as the description proceeds.

The invention will be disclosed in connection with a sash similar .to'that shown and claimed in my Patent No.` 1,570,702, dated Janna 26th, 1926, some features of the sash being modified in accordance with my application on Serial No. 98,187, filed March i 29, 1926.

:[n'the accompanying'.v drawing, forming a part of this slecification, Fig. 1 is a crosssection of a s embodying my invention;

`1.2?. Fig. 2 is a erspective view of a stiflening i dPin-the device shown in Fig. 1;

bracket use Fig. -3 is a View similar to Fig. 1 showurg a modified form of m invention; Fig. 4 1s a perspective view o the stiffening member shown in Fig. 3.

The sash shown is adapted to be applied to a window frame member 10 having its supporting surface perpendicular to the edge of the glass 11. The sash consists of an ining mem r 13. The inner clam ing member has an upper flange 14 exten ing to the surface of the glass and a flange 15 on the edge of portion 14 adapted to lie against the face of pane 11. Clamping member 12 has a flange 16 on its other edge adapted to lie against supporting member 10. The front clampin member 13 has a flange 17 at 1ts upper e ge adapted to contact the face of the glass substantially opposite flange 15. At its lower edge clamping member 13 has a bead 18 adapted to rest against the surface of supporting member 10 and against the front edge of flange 16. A flange 19 extends inward from bead 18 at a slight distance above flange 16.

Within the rear clampingy member 12 there is arranged a bracket member 20 similar to that disclosed and claimed in the aforesaid patent, and which need not beparticularly ner clam ing member 12 and an outer clampdescribed in this ap lication exce t that it forms a substantial y box sha member open at its front to receive the horizontal arm of an L-shaped member 21. This arm of member 21 has a cam surface 22 adapted to be contacted by a screw 23 threaded through a bushing 24 in the upper wall of bracket 20. The other arm ofl member 21 terminates in an end 25 adapted to fit against flange 17 and hold it against the lass. At its angle, member 21 1s provide with an opening 26 ada ted'to receive an u turned portion 27 of an e 19 so that, w en the screw 23 is driven own, it draws the outer clamping member against the glass and against supporting member 10 and. flange 16.

The construction thus far described is similar to that shown in my aforesaid applications, and, therefore, is not claimed in the present application exce t in combination with the features hereina ter described.

The sashes in the aforesaid applications were intended for use with a riser member in position to support the. rear of clamping member 12. In order to stifen the construction so that the device may be used in the absence of such a riser, I rovide a. stiening member 28 adapted to t within bracket member 2O and hold it in proper relation to supporting member 10. The stiffenin member 28 comprises a plate 29 adapte to lie upon the bottom lwall of bracket 20 and having a forwardly extending portion 30 adapted to lie upon flange 16. Portion 30 is provided with a hole 31 through which a screw 32 may be driven into supporting nember 10 to hold the stiffening member in p ace.

In the form shown in Fig. 2, flanges 33 rise from' the sides of portion 29 and fit within and against the side walls of bracket 20. At the u per edges of flan es 33 there are inturned fiiinges 34\which fit neath and against the up er wall of bracket 20 on the two sides' of ushing 24. Preferably the 100 parts are so arranged that the front ends of flanges 34 rest against the lower edge of flange 15.

As will be readily seen, the bracket 20 and stiffeningmember 28 may be readily slipped 105n into posit1on within the rear clamping member 12. A series of such brackets and stiening members arranged along the length of clamping member 12 suflices to secure it in posit1on and hold it in proper relation to 11 supportingzmember 10, a single screw 32 for each stiiening member being sutlielent for this purpose. Thereafter the glass may be )ut 1n ositionfand a front clamping memer witi its draw 'plates` 21 may be thrust into proper relation with the front of the pane, and tightening screw 23. secures the front clamping member m position.

It will be readily seen from the above that I have provided a simple stii'ening member by means of which a sash such as disclosed in the above mentioned applications may be readily converted into a self supporting sash. It will be further seen that the attachment .of this self supporting sash may be made very readily and with a high degree of `accuracy without requiring excessive skill.

The construction shown in Fig. 3 is similar to that shown in Fig. 1 except that a di'erent form of stilening member is used. The stiffening member shown in Figs. 3 and 4 has a lower plate 35 with a front extension 36, similar to plate 29 and extension 30 of the member shown in Fig. 2, but instead of having anges rise from the sides of late 35 it is provided with a ange 37 rising rom the rear end of plate 35. At the top of flange 37 there is a forwardly turned liange 38 notched at 39 to fitaround bushing 24. The stiflening member shown in Fig. 4 is more simple and more cheaply constructed than that shown in Fig. 2, but as will be obvious must be made of stiffer material in order to effect the same amount of stiening of the sash. The member shown in Fig. 4 may be used where it is suliicient to accomplish the desired purpose, but for heavier dlljllty the member shown in Fig. 2 is prefera e.

While the terms used in the foregoing description are suitable for a construction wherein supporting member 10 is the sill beneath the pane, it will be readily understood that the same sash construction may be used at the sides or top of the glass.

It will be readlly understood that various changes may be made in the clamping members and in the shape and construction of bracket 2O and in the arrangement of the stiifening member within the scope of the appended claims, which state what I claim as my invention.
